Applications

SOMATEC web accumulators ensure continuous material flow in every converting line — the buffer between process steps.

Coating lines — Buffering between unwinder and coating station for uninterrupted roll changes
Lamination lines — Compensating speed differences between lamination and winding station
Printing lines — Continuous web run even during roll changes or format changes
Calendering lines — Buffering between calender and winding for constant line speed
Converting lines — Wherever two process steps operate at different speeds

Why the ACC-HD?

With up to 200 m storage capacity and 4,500 mm working width, the ACC-HD is the most powerful accumulator in the SOMATEC series. The double-loop design enables compact footprint despite high capacity. Mechanical or pneumatic weight compensation of the roller carriage ensures sensitive control.

Typical Configurations

Nonwoven line: ACC-HD with double loop and 200 m capacity for long roll change times with wide webs
Heavy-duty production: ACC-HD with infeed and outfeed pull rolls and web edge guiding
Large format: ACC-HD with up to 4,500 mm working width and pneumatic weight compensation

Frequently Asked Questions

When is the heavy-duty accumulator needed? — When particularly heavy webs (e.g. thick PVC flooring, roofing membranes, heavy composite films) need to be buffered. The ACC-HD is designed for high web weights and tensions.
What structurally distinguishes the ACC-HD? — Reinforced roller bearings, more robust frame structure and higher drive power. For applications where standard accumulators reach their mechanical limits.
Can SOMATEC recommend the right accumulator variant? — Yes — we analyze material, web weight, speed and buffer requirements and recommend the appropriate ACC variant.
